Re: Kernel 2.6.24-14 and -15 won't boot

I have been seeing that problem around this forum lately so I just boot from the .14 kernel for now (mine works

)

Hardy is still beta so I am sure this issue will be resolved shortly.

I see you have posted the issue with launchpad so you should be getting a few responses within due time

Re: Kernel 2.6.24-14 and -15 won't boot

I shall wait patiently then.
the -12 kernel works fine as far as I can tell (whatever that means

)

Thanks for your reply

Re: Kernel 2.6.24-14 and -15 won't boot

When I accepted the upgrade for the -15 kernel, and when it offered me the new Grub boot menu, I "accepted the package maintainer's version". That was a mistake. For reasons unknown, it wrote a "rootflags=data=writeback" option into the menu.lst, and also on the kernel boot line. That caused mine to "mis-boot" to the busybox. Removing the rootflags option, and fixing the kernel boot line, restored the correct boot into the -15 kernel.

I'm tossing this out in case it is a problem for others.

Re: Kernel 2.6.24-14 and -15 won't boot

Where would I find those options? How do you fix the kernel bootline?

This is my menu.lst

Code:

# menu.lst - See: grub(8), info grub, update-grub(8)
#      grub-install(8), grub-floppy(8),
#      grub-md5-crypt, /usr/share/doc/grub
#      and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not use 'savedefault' or your
# array will desync and will not let you boot your system.
default		0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout		10

## hiddenmenu

Can you tell me if your problem appears here too?

Re: Kernel 2.6.24-14 and -15 won't boot

You did not get bitten by the same critter. If you had the problem, it would appear here:

# defoptions=quiet splash rootflags=data=writeback

and again here:

kernel /boot/vmlinuz-2.6.24-15-generic root=UUID=9c60e178-a4eb-48d0-936e-2b962c7f48e3 ro quiet splash rootflags=data=writeback

Re: Kernel 2.6.24-14 and -15 won't boot

Ok thanks

guess it's waiting for someone else here or at
launchpad to have an idea which critter it was here

Re: Kernel 2.6.24-14 and -15 won't boot

@BlueRose -- check your /etc/fstab file, and see whether there has been a change to your UUID numbers. The UUID number for /dev/hd07 must be a match to the UUID shown on the kernel boot line above. If they don't match, change the one it /boot/grub/menu.lst to match /etc/fstab.

**dibl** · Apr 07, 2008, 09:01 AM

Re: Kernel 2.6.24-14 and -15 won't boot

Aha! The problem has been found by Rog131, here:

http://kubuntuforums.net/forums/inde...seen#msg125145

In etc/fstab, you must use "UUID=UUID=9c60e178-a4eb-48d0-936e-2b962c7f48e3" to mount, or else "/dev/sd07"

**BlueRose** · Apr 07, 2008, 10:20 AM

Ok before I screw things up

this is currently my /etc/fstab (running the -12 kernel)

The #comments are a bit weird.. The partitions mounted to windows, programs and archive should be hdaX (all on my 160GB IDE disk.. and the ones mounted to documents, music, movies, installs, ebooks should be sdaX.. which is my 500GB SATA disk.

The UUID's in mune.lst are the same for all 3 kernel versions, so I don't think there's the problem. it boots one fine.. however my fstab is weird? Not sure, I have no experience with that, and before I can't enter my system anymore I rather spam here again and let you look over it and tell me if there's something wrong and how to fix it (if you would be so kind

, you have been so far)

**dibl** · Apr 07, 2008, 10:35 AM

Re: Kernel 2.6.24-14 and -15 won't boot

Meh -- it's not jumping out at me what's wrong.

The distinction between "h" and "s" for hard drives is history -- you might as well forget what you once knew about IDE drives and SCSI drives and SATA drive designations. They're all "s" now, for /etc/fstab purposes. Grub still thinks they're all "h", however.

But, since you are mounting by UUID, that's irrelevant, and your UUIDs match, so that's not the problem.

I think the "1" at the end of the root mount line in /etc/fstab should be a "2" but again that's irrelevant to booting.

Have you to tried to boot -15 in "recovery" mode?

**BlueRose** · Apr 07, 2008, 10:38 AM

Re: Kernel 2.6.24-14 and -15 won't boot

I haven't yet, but I could do that now of course

I'll update shortly how that worked out

EDIT: I just rebooted the recovery version of the -15 kernel..
It got to
[163.253046] /build/buildd/linux-2.6.24/driver/hid/usbhid/hid-core.c: v2.6:USB HID core driver
<took a minute>
Done

and then came the error again:
Check root= bootarg cat /proc/cmdline
or missing modules, devices: cat /proc/modules ls /dev
ALERT! /dev/disk/by-uuid/9c60e178-a4eb-48d0-936e-26962c7f48e3 does not exist.
Dropping to a shell!

Busybox 1.1.3 (Debian 1:1.1.3-5ubuntu12) Built-in shell (ash)
Enter 'help' for a list of built-in commands

(initramfs)_

So same as the normal boot method I guess..
I'm back in 2.6.24-12 now

**BlueRose** · Apr 07, 2008, 10:54 AM

Re: Kernel 2.6.24-14 and -15 won't boot

dibl: Why do you think it should be a 2 in fstab? what does the 2 mean?
(just curious, wanna learn where I can

**dibl** · Apr 07, 2008, 02:58 PM

Re: Kernel 2.6.24-14 and -15 won't boot

The last digit in the mount line for each hard drive partition is the "Files System Check" order value, or "Fsck order".

Fsck: Fsck order is to tell fsck what order to check the file systems, if set to "0" file system is ignored.

However, upon looking this up, and then looking your /etc/fstab file again, I was wrong -- the oddball is not the root filesystem, which should be a "1" just like you have it. The oddball is the other hard drive partitions, which would normally be "2" like your /home partition is. I don't know why those NTFS partitions are all set at "1".

But it's no big deal the way you have it, and I don't believe it is relevant to the booting problem, which must related to a change in the kernel that affects your hardware somehow.

**BlueRose** · Apr 09, 2008, 11:31 PM

Re: Kernel 2.6.24-14 and -15 won't boot

Ok, I think it's been fixed.. the guys at launchpad told me to try to tka ethe jumper off of the hard disk. Set my pata drive in single driver mode (the disk on which my root partition is). Something weird with Western Digital drives.. anyways. IT WORKED

I'm in kernel -15 now.

And even better: loading grub doesn't take so long anymore!
I had 30sec between post and grub loading stage1.5, then 30sec nothig again, then loading grub

lease wait (another 20sec or so) before I finally hit the boot menu.. with the jumper gone.. it only took 10 seconds tops from post to menu

now that's what I call happy waking up

I think this might have been the reason that the openSUSE installer didn't see my pata disk either, just my sata disk.. oh well

Thanks again for your help guys
